SPECIFICATEON forming part of Letters Patent No. 661,741, dated November 13, 1900.

Application filed March 28, 1900. Serial No. 10,517. LND model.)

To all whom, t may con/cern:

Be it known that I, GEORGE A. LAMBERT, a citizen ofthe United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Vehicle-Poles, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure l is a plan view of the rear portion of the pole; and Fig. 2 is a side elevation thereof, partially in section.

The object of the invention is to provide a carriage-pole with a sectional circle-bar which may be readily adjusted to thills which are various distances apart and to so construct and brace the circle-bar that it will be very stiff and rigid, the brace-rods being so secured thereto that they will take all the strain put on the thill-eyes, and thereby relieve all the pivotal connections of the circle-bar.

Referring to the various parts by numerals, l designates the pole, and 2 the two-part circle-bar, which is forlned in two sections pivotally connected at their inner ends to the rear end of the pole. To the outer free ends of these circle-bar sections are pivoted at 3a the rearward and outward curved extensionarms 3. arms are pivoted the thill-eyes 4. To the outer sides of these extension-arms are rigidly bolted or riveted or otherwise suitably secured the rear ends of the brace-rods 5, whose forward ends are connected together and are adjustably connected to the pole by means of the clamp-nut 7 and bolt 6.

When it is desired to adjust the thill-eyes to the thill-irons on the vehicle-axle, the clampnut is loosened to free the forward ends of the braces, and then the thill-eyes are moved outward or inward, as desired, to lit the thillrons, and then the clamp-nut is again tightened. By pivoting the arms 3 on the outer ends of the two-part circle-bar sections the brace-rods may be rigidly bolted at their rear ends to the outer sides of the said arms 3 without interfering with the adj ustability of the circle-bar, the pivotal joints between the circle-bar sections and the arms 3 permitting the said arms and the circle-bar sections to be swung outward without buckling the brace- To the rear ends of these extension-A disadvantage of such a structure is that the pivotal joints will soon wear under the strains brought on them and become loose and rattle. By connecting the brace-rods at their rear ends rigidly to the extension-arms and clamping them to the pole at their forward ends all strain put on the thill-eyes will be transferred directly to the rigid fastening means of said rods, thus relieving the pivotaljoints entirely of all strain. It will thus be seen that while the circle-bar may be readily adjusted in width, all strains brought on the thill-eyes will be taken up by the rigid connections of the brace-rods, the pivotal joints between the circle-bar sections and the arms 3 being entirely relieved of all strains.

By connecting together the forward ends of the brace-rods and adjustably connecting them at their connected ends to the pole l an equal adjustment of the thill-eyes is assured, there being no danger of one thill-eye being adjusted nearer to the pole than the .other eye, as might be the case were each eX- tension adj usted independently of the other.

The advantage of securing an absolutely equal adjustment of these extension -arms will be readily seen. If these arms are not evenly adjusted, the pole will be thrown od the center and the strain will be brought more on one thill-eye than on the other.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In an adjustable vehicle-pole the combination of a pole, a circle-bar secured to the rear end of said pole, extension-arms pivoted to the outer ends of said circle-bar, brace:

rods rigidly bolted at their rear ends to said extension-arms and connected together at their forward ends, and means for adj ustably clamping said braces to the pole at their connected ends, whereby said extension-arms ICO may be simultaneously and uniformly adjusted, and whereby all strain brought on the 2. In an adjustable Vehicle-pole the corn-V bination of a pole, a circle-bar secured to the rear end thereof, said bar being formed of two sections pivoted at their inner ends to the pole, extension-arms pivoted to the outer ends of the circle-bar, thill-eyes pivoted to the rear ends of the extension-bars, and bracerods rigidly connected to the said extensionarms, and adjustably clamped to the pole, whereby strain put on the thill-eyes will be transferred to the rigid non-pivotal fastening means of the brace-rods, thereby relieving the ,pivotal connections between the extension-arms and vthe circle-bar.

3. In an adjustable vehicle-pole the combination of a pole, a two-part circle-bar secured to the rear end of said pole, extensionarms pivoted to the outer ends of said circlebar, brace-rods rigidly secured attheir rear ends to said extension-arms and connected together at their forward ends, and means for adjustably clamping said connect-ed forward ends to the Vehicle-pole.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 26th day of March, 1900.

GEORGE A. LAMBERT.
